– the likely deduction of any costs involved in recovery of amounts outstanding;
– the ability of the borrower to obtain, and make payments in, the currency of the loan if not denominated in
local currency; and
– when available, the secondary market price of the debt.
The realisable value of security is determined based on the current market value when the impairment
assessment is performed. The value is not adjusted for expected future changes in market prices; however,
adjustments are made to reflect local conditions, such as forced sale discounts.
Impairment losses are calculated by discounting the expected future cash flows of a loan at its original effective
interest rate and comparing the resultant present value with the loan’s current carrying amount. The impairment
allowances on individually significant accounts are reviewed at least quarterly and more regularly when
circumstances require. This normally encompasses re-assessment of the enforceability of any collateral held and
the timing and amount of actual and anticipated receipts. Individually assessed impairment allowances are only
released when there is reasonable and objective evidence of a reduction in the established loss estimate.
Collectively assessed loans and advances
Impairment is assessed on a collective basis in two circumstances:
– to cover losses which have been incurred but have not yet been identified on loans subject to individual
assessment; and
– for homogeneous groups of loans that are not considered individually significant.
Incurred but not yet identified impairment
Individually assessed loans for which no evidence of impairment has been specifically identified on an
individual basis are grouped together according to their credit risk characteristics for the purpose of calculating
an estimated collective impairment. These credit risk characteristics may include country of origination, type of
business involved, type of products offered, security obtained or other relevant factors. This reflects impairment
losses that HSBC has incurred as a result of events occurring before the balance sheet date, which HSBC is not
able to identify on an individual loan basis, and that can be reliably estimated. These losses will only be
individually identified in the future. As soon as information becomes available which identifies losses on
individual loans within the group, those loans are removed from the group and assessed on an individual basis
for impairment.
The collective impairment allowance is determined after taking into account:
– historical loss experience in portfolios of similar credit risk characteristics (for example, by industry sector,
loan grade or product);
– the estimated period between impairment occurring and the loss being identified and evidenced by the
establishment of an appropriate allowance against the individual loan; and
– management’s experienced judgement as to whether current economic and credit conditions are such that
the actual level of inherent losses at the balance sheet date is likely to be greater or less than that suggested
by historical experience.
The period between a loss occurring and its identification is estimated by local management for each identified
portfolio.
Homogeneous groups of loans and advances
Statistical methods are used to determine impairment losses on a collective basis for homogeneous groups of
loans that are not considered individually significant, because individual loan assessment is impracticable.
Losses in these groups of loans are recorded on an individual basis when individual loans are written off, at
which point they are removed from the group. Two alternative methods are used to calculate allowances on a
collective basis:
− When appropriate empirical information is available, HSBC utilises roll rate methodology. This
methodology employs statistical analyses of historical data and experience of delinquency and default to
